Peugeot 407 2.2 (EW12) Petrol Engine Diesel Noise..VVT Gear Assembly Failure?

Post by AlvinCitroenC5 »

Hi,

It has been sometime that my 2007 407SW 2.2 Petrol has been making a diesel noise / rattle. This is especially apparent during cold start or high RPM. To my understanding, the sound is caused by a failing VVT Cam Gear. I am wondering, how bad should things get before I spend the money to replace it? Since it is a quite an expensive part. I also notice a flat spot during full throttle when my engine accelerates between 3700RPM to 4100RPM. And fuel mileage has not been great, I average 12.9L/100Km, which in my opinion is very high.

Your suggestions are greatly appreciated.

Thanks.
